Astra Streaming does not set YouTube’s video-upload limits. If you mean uploading a long video to YouTube, the account must be verified for videos over 15 minutes, and each upload must stay within YouTube’s maximum of 256 GB or 12 hours, whichever limit is reached first. Astra Streaming’s limits apply to streaming data messages and retention—not YouTube video files.
Which “Astra Streaming” do you mean?
DataStax Astra Streaming is a managed streaming-data service. YouTube is a video platform with its own upload rules. The two services do not share an upload quota: Astra’s message-size and retention settings neither increase nor reduce the size or duration of a YouTube video you can upload.
If you came here to upload a long video to YouTube, use the YouTube limits below. If you are configuring DataStax Astra Streaming, its separate data limits are summarized afterward.
YouTube’s limits for long video uploads
YouTube Help’s guidance, checked October 3, 2026, says accounts can upload videos up to 15 minutes by default. To upload longer videos, verify the account. The maximum upload is 256 GB or 12 hours, whichever limit is reached first. A video must meet both limits; being under the file-size cap does not allow a video longer than 12 hours, and a shorter video still cannot exceed 256 GB. YouTube notes that older videos longer than 12 hours may remain available because its upload limits have changed over time. YouTube Help: Upload videos longer than 15 minutes

Check eligibility before uploading
- Verify the YouTube account if the video is longer than 15 minutes, following YouTube’s account verification process.
- Check the file’s duration and size before uploading. It must be no more than 12 hours and no more than 256 GB.
- On a computer, use an up-to-date browser for files larger than 20 GB, as YouTube’s computer upload guidance advises.
If you previously uploaded videos longer than 15 minutes but cannot do so now, YouTube advises checking the account for copyright claims or strikes. Resolve any account restrictions shown in YouTube Studio before trying again.
If the file is too large
YouTube recommends using video-editing software to compress a file that exceeds 256 GB and names H.264 as an option. Compression can reduce file size, but check the resulting duration and file size against both YouTube limits before uploading. YouTube Help: Upload videos

What Astra Streaming limits actually cover
DataStax’s Astra Streaming limits documentation, checked October 3, 2026, describes limits on data messages and namespace storage policies, not video uploads. Do not compare its message-size or backlog figures directly with YouTube’s video-file upload ceiling: they measure different things.
| Astra Streaming setting | Documented limit or default | What it means |
|---|---|---|
| Maximum message size on shared clusters | 5 MB | A limit for an individual streaming-data message on a shared cluster, not a YouTube video. |
| Message size on Streaming Capacity Units | Customizable | Dedicated-unit configurations have a customizable message size; consult the applicable configuration and limits documentation. |
| Namespace retention | Disabled by default | Retention is a configurable policy for Astra data, not YouTube storage. |
| Default backlog size | 5 GB | Astra’s documented default backlog setting, not a video-upload allowance. |
DataStax’s documentation also distinguishes shared clusters from dedicated Streaming Capacity Units for constraints such as message size and throughput. Retention settings can affect charges; consult the current Astra Streaming limits documentation and Astra Streaming pricing documentation for configuration and billing details. The pricing page metadata is dated June 19, 2026; the limits page does not state a publication date.

Or let it run in the cloud
If the goal after uploading is to keep a YouTube channel live around the clock with pre-recorded video, StreamNeo is a separate service—not an Astra Streaming feature. Upload a recording or build a playlist, add your YouTube stream key once, and go live; StreamNeo loops the uploaded video from the cloud, so your computer and home connection do not need to stay on.
